HAIR-DYE.

No Drawing.

To all whom it may concern:

Be it known that we, LOUISE SEAGO and ALBERT SEAGO, both subjects of theKing of Great Britain, and residents of the borough of Manhattan, city,county, and State of New York, have invented certain new and usefulImprovements in Hair -Dyes, of which the following is a specification.

This invention has for its object to provide an improved dye which issimple in its application, permanent in its retaining qualities andnoninjurious to the user.

Hitherto the dyeing of human hair was attended with a great deal ofinconvenience in that it required the application of several chemicalsto bring about a permanent bleach of satisfactory character, theapplication of each of which chemical had to be alternated with a hotwater and hot air treatment. All of this required very often a greatdeal of time necessitating the repeated manipulation of the sensitiveroots and consequent inflammation of the scalp. The further objectionwas that the hair would become broken and split and thus the hairs wouldbe destroyed. The further and greatest objection to the bleachingmethods hitherto used was that by reason thereof it could always bereadily recognized that the hair was not of the natural color, and forthis reason many refrained from bleaching for fear of having the factperceived.

The object of our invention is to provide an improved hair-dye whichwill not be accompanied by these disadvantageous features but which isso arranged that on the single application of it, the hair will obtainthe desired color, and will retain this color. Furthermore, our improvedinvention has the advantage of giving a natural color to the hair andretaining at the same time'the natural flexibility of it, as also thenatural gloss, with the further advantage that instead of the hair beingdeteriorated, the dye acts as a hair invigorator and strengthener.

The further advantage of our improved hair-dye is that when it is againdesired to obtain the natural color and remove the dye, this may bereadily done by suitably washing the hair with a restoring solution, by

which operation the hair is restored to its natural color.

This invention consists of an improved hair-dye which is obtained bypreparing an aqueous solution of permanganate of potash in theproportion of one-half an ounce of crystals to one-quarter of a pint orapproximately four ounces of water, and adding a half ounce more or lessof common salt to this solution, and applying this solution to the hair.The common salt acts as a stimulant to the hair follicles and tends toprevent decomposition of the other salt. After it has been applied, thehair is allowed to dry and the dye thereby sets. If a different shade bedesired, it is necessary to add more 7 or less water, depending on thedarkness or lightness of the shade desired, the greater amount of waterweakening the solution and consequently weakening the dyeing qualitiesof the solution, whereas a less quantity of water causes theconcentration of the solution and a darker shade of the hair.

By the use of our invention it is not necessary to first wash the hairor in any way prepare it, since the germicidal qualities of the improveddye entirely disinfect and cleanse the hair at the time of dyeing thesame, and for this reason a preliminary treatment of the hair isunnecessary.

The great advantage of the dye is that it is immediate in its operationand quick in application, and retains the natural gloss of the hairwithout in any manner having a bad influence on the hair.

In case it is desired to remove the dye all that is necessary is-toapply a restoring solution of peroxid of hydrogen or citric acid, inwhich case the action of the dye is counteracted and the natural colorof the hair again obtained.

We have found by many tests that when permanganate of potash is usedalone for the purpose of dyeing hair, the result is the return of thehair to its natural color or approximately so within a very shortperiod; whereas when common salt is added to the permanganate of potashand the compound thus formed is used for the dyeing of hair, the hairremains in properly dyed condition for a long period. The salt thusrenders a In testimony, that We claim the foregoing fugitive dyepractically permanent. as our invention, We have signed our names 10Having thus described our invention, We in presence of two subscribingWitnesses. claim as new and desire to secure by Letters LOUISE SEAGO. 5Patent: ALBERT SEAGO.
